Embodiment 1
[0026] Embodiment 1: A method for enriching and purifying the volatile oil of Atractylodes atractylodis by using the coupling method of batch distillation-macroporous adsorption resin, the steps are as follows:
[0027] (1) After the dried herb is crushed and passed through a 60-mesh sieve, the dried herb is heated to boiling with purified water according to the ratio of material: water = 1:6, the oil-water mixture is condensed into a distillate and flows out through the condenser, and distilled for 4 hours;
[0028] (2) the herb distillate processed in (1) flows into the oil-water separator for separation;
[0029] (3) Collect the distillate flowing out of the water outlet pipe, carry out double distillation, and distill for 3 hours; collect the volatile oil of Atractylodes atractylodis flowing out from the inlet pipe, combine it with the volatile oil of Atractylodis atractylodis obtained from double distillation, mix evenly, let stand, and suction filter , concentrating unde...

[0035] Implementation Case 2: A method for enriching and purifying the volatile oil of Atractylodes Atractylodis by using the coupling method of batch distillation-macroporous adsorption resin, the steps are as follows:
[0036] (1) Grind the dried herb and pass through a 10-mesh sieve, heat the dried herb with purified water according to the ratio of material: water = 1:6 until boiling, the oil-water mixture is condensed into a distillate and flows out through the condenser, and distilled for 4 hours;
[0037] (2) the herb distillate processed in (1) flows into the oil-water separator for separation;
[0038] (3) Collect the distillate flowing out of the water outlet pipe, carry out double distillation, and distill for 3 hours; collect the volatile oil of Atractylodes atractylodis flowing out from the inlet pipe, combine it with the volatile oil of Atractylodis atractylodis obtained from double distillation, mix evenly, let stand, and suction filter , concentrating under redu...
Embodiment example 3
[0044] Implementation Case 3: A method for enriching and purifying the volatile oil of Atractylodes Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodis by means of coupling method of batch distillation-macroporous adsorption resin. The steps are as follows:
[0045] (1) After the dried herb is crushed and passed through an 80-mesh sieve, the dried herb is heated to boiling with purified water according to the ratio of material: water = 1:6, the oil-water mixture is condensed into a distillate and flows out through the condenser, and distilled for 4 hours;
[0046] (2) the herb distillate processed in (1) flows into the oil-water separator for separation;
[0047] (3) Collect the distillate flowing out of the water outlet pipe, carry out double distillation, and distill for 3 hours; collect the volatile oil of Atractylodes atractylodis flowing out from the inlet pipe, combine it with the volatile oil of Atractylodis atractylodis obtained from double disti...
